Waterfall Crash [java.lang.RuntimeException: VarInt too big]

[AutoComplete1]

Hello,
currently our bungeecord is crashed after my research with the help of wrong packets. The crash is so that the proxy is not reachable for about one minute and is then reachable again. Here's the exception:

It is not related to the proxy itself, someone is sending invalid packets

@xxDark I am aware of this, but I have a problem with the fact that the proxy is not reachable for about one minute and all players are getting kicked. If only the error in the console would come, I wouldn't have a problem with it.
